mr_00ff00··on Children's arithmetic skills do not transfer between applied and academic math
“Regression results suggest no statistically distinguishable relationship between IQ scores and wealth. Financial distress, such as problems paying bills, going bankrupt or reaching credit card limits, is related to IQ scores not linearly but instead in a quadratic relationship. This means higher IQ scores sometimes increase the probability of being in financial difficulty.”

Notice how I cited a source, that’s intelligence. Not just decided I was wealthy and therefore inherently smarter. That’s ignorance.

I grew up in one of those small hometowns that sends a lot of people to the close by Ivy League school.

It was an open secret that getting a learning disabilities diagnosis is a great SAT booster. Also makes you eligible for more time on regular school exams and you can use it to later get more on the LSATs (not sure about other grad level exams, but I am sure it’s similar)

This idea that school is signaling is spread so often, but so much shows it’s not true.

The thing that correlates highest with SAT score is household income.

Household income is also a strong indicator of GPA, school competitiveness, and college attended.

I suspect those with money that like the current system spread this information because it makes them feel their success is their own, and not because it was given to them.

Unless you are a social Darwinist who believe the poor are genetically worse…

mr_00ff00··on Google drops pledge not to use AI for weapons or surveillance
Technically the US has never dropped nukes, those were atomic bombs.

Second, don’t understand how the atomic bomb argument makes sense. Germany was developing them and would have used them if it got there first.

Are you suggesting the US really is truly the only nation that would ever have used atomic weapons? That if Japan made it first they would have spared China or the US?

mr_00ff00··on Roc rewrites the compiler in Zig
I remember reading the HN thread when Fish rewrote to Rust. A big reason because “they wanted to stay current” so they rewrote from C++ to Rust.

Someone made a joke comment how in a few years there would be tons of HN threads about rewriting Rust to Zig.

mr_00ff00··on Ask HN: What is interviewing like now with everyone using AI?
So depressing to hear that “because of rampant cheating”

As a person looking for a job, I’m really not sure what to do. If people are lying on their resumes and cheating in interviews, it feels like there’s nothing I can do except do the same. Otherwise I’ll remain jobless.

But to this day I haven’t done either.

mr_00ff00··on Falsehoods programmers believe about null pointers
“Most important optimization is developer time and code cleaniness”

True for 99% of programming jobs, but if you are worried about the speed of null checks, you are in that 1%.

In high frequency trading, if you aren’t first your last and this is the exact type of code optimizations you need for the “happy path”

mr_00ff00··on Ross Ulbricht granted a full pardon
https://www.bop.gov/inmates/fsa/overview.jsp

Feel like you have already made up your mind on what you want to believe, but he has actually helped a lot with non-violent drug offenders. That’s part of the reason poor communities (especially Latino) have voted for him despite harsh border policies.

mr_00ff00··on TikTok says it is restoring service for U.S. users
This feels like a stretch, I don’t think it’s a pardon they are after. Pardons don’t really work like that.

TikTok I think was going for more of a shock factor. Maybe even without talking to Trump they have credited him as restoring it, might seem weird for him to “go back on it”.

Or maybe it’s to put him in good light.

mr_00ff00··on About availability of TikTok and ByteDance Ltd. apps in the United States
Wow that actually surprises me. Social media had me thinking it was very one sided.
mr_00ff00··on About availability of TikTok and ByteDance Ltd. apps in the United States
As a counter argument (and not saying this is right)

This creates a vacuum of time that Americans now can use on other tech apps. American leisure hours is a finite resource, in a way TikTok competes with Netflix, Meta, and even sports.

That’s revenue in other areas.

mr_00ff00··on About availability of TikTok and ByteDance Ltd. apps in the United States
Will admit, this is a big PR win for him if it works.

Especially since a lot of young voters / voters in general don’t see much of the impact of the president.

Him doing something popular that the average person can see seems like a huge win.

mr_00ff00··on Great things about Rust that aren't just performance
I feel like your last point is the exact issue with exceptions, not rust’s errors. Exceptions are like having “?” on every single line.
mr_00ff00··on NYC Congestion Pricing Tracker
You are wealthy if you are using private car services like that.

Most normal New Yorkers use the subway

mr_00ff00··on NYC Congestion Pricing Tracker
The people paying the congestion fees are the rich that live in the suburbs and drive into the city.
mr_00ff00··on After twelve years of writing about Bitcoin, here's how my thinking has changed
I feel like I might be similar to a lot of HN.

I saw the crypto hype about how the entire world was about to run on web3 and knew it made no sense.

That made my opinion of crypto as ‘tons of people with no understanding of technology or the real world’

That cooled off and then watched the opposite. Tons of people tell me bitcoin would hit 0 even though it had been useful far before the 2021 hype.

Now I don’t know how I feel. Bitcoin has a fixed supply and I think it can serve as a store of wealth in that way if we all agree to it (author sort of disagrees with this).

I’m realizing I’ve maybe met other people decide for me how I feel about it.

mr_00ff00··on Rust Needs an Official Specification
I get the author’s point so this may be a useless nitpick but I am not surprised in Rust that drop is called immediately when a value is assigned to _.

That’s almost like calling delete in c++ and if you changed the C++ code to a class with a print in the destructor, then called “delete” you would get the same behavior.

The “just” underscore in rust I believe is special and basically makes that value inaccessible. So that value really does “destruct” there.

mr_00ff00··on Study: Dark matter doesn't exist, the universe is 27B years old
Aren’t you sort of proving the opposite?

You say that they saw books get printed faster, so they could conceive communication getting so fast it’s instant, despite their knowledge being limited to physical material.

By the same logic, couldn’t I say we have theorized wormholes and have already seen objects (like black holes) warp time and space? Therefore maybe we can warp space to travel, rather than literally needing to go faster than light?

I think it’s easier for us now to conceive the idea that one day we could make a wormhole than it is for people with no concept of radio waves to conceive the idea of a cellphone.

mr_00ff00··on Study: Dark matter doesn't exist, the universe is 27B years old
This entire theory seems to be based on only current technology.

Tell someone in the 1600s about the concept of cellphones and they would say it’s impossible to ever instantaneously communicate with someone around the world.

It’s so energy intensive with our current technology, which isn’t really an answer to fermi.

mr_00ff00··on Julia for Economists (2022)
As someone who started to study economics and switched into computer science, can anyone explain why Stata is used for most economics work when Python/Julia/R seem like such better options and are free?
mr_00ff00··on Employees who stay in companies longer than two years get paid 50% less (2014)
They mentioned “average” vs best employee, and the raises each can expect.

So that at least seems to imply that they adjust for that. Specially the line where you can get a 1% raise or a 10% new offer.

mr_00ff00··on Global tourism is booming. These people would rather it wasn't
Maybe I made it seem like I was implying that’s a universal rule.

What I meant was many people jumped to say it was only money that caused people not to travel. Everyone knows a friend like mine. I have no idea of the breakdown, but my personal experience makes me want to question the idea it’s always all money.

mr_00ff00··on Global tourism is booming. These people would rather it wasn't
A lot of replies are claiming it’s money, but honestly I think there’s just a lot of people that don’t care to see the world beyond their town.

I have a friend that grew up, went to college, went to law school all within 20 miles of his hometown. As soon as he graduated law school, he got married and started talking about having kids. That was a few years ago, but he was basically 45 and settled into his suburban life at the age of 24.

mr_00ff00··on Leaving Rust gamedev after 3 years
Sort of, although Zig certainly pushes itself towards the embedded world. I have tried Zig a bit and like it a lot, and I am sure it would be better for game dev than Rust, but I don't want to pass allocators around all day to all the objects in my game.

Go without GC is more like a Go and Zig baby.

mr_00ff00··on Improvements to static analysis in GCC 14
I know Rust (esp on HN) is very hyped for its memory safety and nice abstractions, but I really wonder how much Rust owes its popularity to its error messages.

I would say the #1 reason I stop learning a technology is because of frustrating or unclear errors.

EDIT: Getting a bit of topic, but I meant more because I love C and would love it more with rust level error messages.

mr_00ff00··on Web Scraping in Python – The Complete Guide
May be misunderstanding what you mean by “browser agents” but I’ve done some web scraping that had dynamic content and it was easy with a simple chrome driver / gecko driver + scraper crate in Rust
mr_00ff00··on “I'm sorry, Dave. I'm afraid that computation is too carbon intensive”
Maybe there’s some term or phrase for this, but I feel like those being wasteful aren’t gonna change because suddenly the goal post is moved.

Maybe I’m too pessimistic, but I feel like most human behavior we decide what we are gonna do and then find the reasons to justify it.

mr_00ff00··on Change F#'s Color on GitHub
There’s already a draft pr for this: https://github.com/github-linguist/linguist/pull/6686
mr_00ff00··on Cutting down AWS cost by $150k per year simply by shutting things off
Would be a random coincidence, but if you work at a large bank, I think I may know the team that had that 300k test db lol.
mr_00ff00··on Why Zig When There Is Already C++, D, and Rust?
I don’t think you can ever argue that a small (and only non-runtime exception, right?) signature at the top of the function makes it easy to see what lines throw.

Even if a function is small, each and every line could be the thrower and not allow the rest to execute.
